Publisher's Synopsis
"Help Me Understand Right Triangles and Plane Trigonometry" is a tutorial and workbook that will help students in a Geometry class better understand the properties of right triangles, both visually and mathematically. This book is not a proof-based approach, but rather a more visual approach to understanding right triangles. (The book assumes that students have a solid understanding of basic Algebra, including exponents, fractions, and radicals) and that the students are enrolled in a middle (junior high) or high school Geometry class.
This workbook include explanations of the following topics. Most sections also include numerous practice problems with fully worked answers.- General Right Triangles & Their Properties
- The Pythagorean Theorem
- Special Right Triangles: Right Isosceles or 45-45-90
- Special Right Triangles: 30-60-90
- Plane Trigonometry or Trigonometry of Right Triangles (SOH-CAH-TOA)
- Perimeter of Right Triangles
- Area of Right Triangles
- Coordinate Geometry with Right Triangles and the Distance Formula
- Inscribed Right Triangles
- Coordinate Geometry with Inscribed Right Triangles
- Circumscribed Right Triangles
- Coordinate Geometry with Circumscribed Right Triangles
- Centroid of Triangles
- Orthocenter of Triangles
